Answer 1

Решение:

1) -18+(-5)= -18-5= -23

2) 10+(-5)= 10-5= 5

3) -33+(-54)= -33-54= -87

4. 68+(-72)= 68-72= -4

5. -25+(-712)= -25-712= -737

6. 762+(-34) =762-34= 728

7. -20+(-357)+(-54)= -20-357-54= -431

8. -51+367+(-79)= -51+367-79= 237

9. -12+(-68)+(-41)+(-99) = -12-68-41-99= -80-140= -180

10. -59+370+8+10= -59+388= 329

Answer 2

Sure, here are the answers to the arithmetic expressions you've provided:

1. -18 + (-5) = -23
2. 10 + (-5) = 5
3. -33 + (-54) = -87
4. 68 + (-72) = -4
5. -25 + (-712) = -737
6. 762 + (-34) = 728
7. -20 + (-357) + (-54) = -431
8. -51 + 367 + (-79) = 237
9. -12 + (-68) + (-41) + (-99) = -220
10. -59 + 370 + 8 + 10 = 329
